IRS Reasonable Cause Penalty Abatement: How to Get Tax Penalties Removed

Written by Yarik Yarosh, CPA (US & Canada) September 5, 2026 · FL CPA license AC61704 · CPA Ontario

IRS penalties aren’t final. The Internal Revenue Code provides two primary paths to penalty removal: first-time penalty abatement (FTA), which requires no explanation beyond a clean compliance history, and reasonable cause abatement under IRC 6651(a) and related sections, which requires demonstrating that the taxpayer exercised ordinary business care and prudence but was unable to comply due to circumstances beyond their control.

Key takeaway

Penalty abatement framework:

First-time penalty abatement (FTA):

  • Available for failure-to-file, failure-to-pay, and failure-to-deposit penalties
  • Requirements: (1) no penalties in the prior 3 tax years, (2) all required returns filed or valid extensions filed, (3) all tax paid or arranged (installment agreement)
  • No explanation needed. The 3-year clean history is the only requirement.
  • Request by phone (call the number on the penalty notice) or by letter
  • Success rate: approximately 90%+ when eligibility criteria are met
  • Can only be used once per penalty type per 3-year cycle

Reasonable cause abatement (when FTA is unavailable):

  • Available for most penalties (failure-to-file, failure-to-pay, accuracy-related, information return penalties)
  • The taxpayer must show: (1) the failure was due to reasonable cause and not willful neglect, AND (2) the taxpayer exercised ordinary business care and prudence
  • Evaluated under IRM 20.1.1.3 (Internal Revenue Manual)

What qualifies as reasonable cause:

  • Death, serious illness, or incapacitation of the taxpayer, a family member, or the tax preparer
  • Fire, natural disaster, or civil disturbance that destroyed records
  • Inability to obtain necessary records (from third parties, government agencies)
  • Reliance on the erroneous advice of a tax professional (the taxpayer must show: they gave the professional complete information, the professional gave specific advice that the taxpayer relied upon, and the reliance was reasonable)
  • IRS error (incorrect information from an IRS agent, misdirected payments)
  • Postal or electronic filing system failure
  • Ignorance of the law (only in limited circumstances where the law is complex, new, or where the taxpayer made a good-faith effort to comply)

What doesn’t qualify:

  • “I forgot”
  • “I was too busy”
  • “I didn’t know I needed to file”
  • “My accountant didn’t tell me” (without specific facts showing the reliance was reasonable)
  • Financial hardship (for failure-to-file penalties; it’s relevant for failure-to-pay penalties)
